Fetal Distress

胎儿窘迫
  • 文章类型: Case Reports
    脐带(UC)对于维持母亲和成长中的胎儿之间的血液循环至关重要,有时会被打乱。脐动脉血栓形成(UAT)是一种罕见的妊娠并发症,可导致极端的围产期结局,从宫内生长受限死胎到新生儿死亡。UAT的产前诊断是必不可少的,有时在临床实践中难以检测。一旦被检测到,在胎儿类固醇肺成熟后考虑通过剖宫产紧急分娩。我们报告了一名被诊断出患有这种罕见妊娠并发症的初产妇,交货时的UAT,连同颈绳和异常卷曲的UC。除了在第二产程中胎膜早破和持续的胎儿窘迫外,患者的妊娠过程顺利。由于分娩过程是最佳的,并优先考虑患者的愿望,在连续电子胎儿监护(EFM)的前提下,她被警惕地观察,以方便任何紧急情况,最终导致一个活着健康的男婴自发阴道分娩。通过EFM检测到的胎儿窘迫是几种压力因素的指标,这些压力因素使胎儿有一些未知的危险,从而增加了围产期死亡的风险。根据我们的经验,建议放射科医师应定期进行常规产前扫描的UC超声检查;产科医生也应对要测量的关键救生超声参数有简短而准确的认识.UAT,颈索,和异常的UC卷绕,就像我们的案子里发现的,都是罕见的因素,在一定程度上与胎儿的发病率和死亡率有关;一旦产前怀疑这种并发症,应该通过密切监测和及时决定适当的交货时间来管理它。
    The umbilical cord (UC) is vital to maintain blood circulation between the mother and the growing fetus, which is sometimes disrupted. The umbilical artery thrombosis (UAT) is an infrequent complication of pregnancy that can lead to extreme perinatal outcomes, ranging from intrauterine growth restriction stillbirth to neonatal death. The prenatal diagnosis of UAT is essential and sometimes challenging to detect in clinical practice. Once it is detected, the emergent delivery through a cesarean section is considered after the steroidal lung maturity of the fetus. We report a primigravida diagnosed with this rare pregnancy complication, the UAT at delivery, along with the nuchal cord and abnormally coiled UC. The patient had an uneventful course of pregnancy except for the premature rupture of membranes and continuous fetal distress in the second stage of labor. As the labor progression was optimal, and prioritizing the patient\'s desire, she was vigilantly observed under the premise of continuous electronic fetal monitoring (EFM) to facilitate any emergency, ultimately resulting in the spontaneous vaginal delivery of an alive and healthy baby boy. The fetal distress detected through EFM is an indicator of several stressors predisposing the fetus to some unknown danger that carries an increased risk of perinatal mortality. Based on our experience, it is suggested that radiologists should routinely conduct UC sonographic studies on regular antenatal scans; obstetricians should also have a brief and precise awareness of the critical lifesaving sonographic parameters to measure. The UAT, nuchal cord, and abnormal UC coiling, as found in our case, are all rare factors and related to some extent of fetal morbidity and mortality; once such complications are prenatally suspected, one should manage it through close monitoring and timely decision of appropriate delivery time.

    肥胖,以过量的脂肪组织为特征,已经成为一个重要的全球健康问题。近几十年来,肥胖症的患病率在全球范围内明显增加。随着发展中国家的急剧上升,特别是在城市地区。由于多种原因,解决怀孕期间的肥胖至关重要,并且对妇产科专家提出了挑战。
    目的:本研究的目的是调查肥胖及其对分娩的影响之间的相关性。
    方法:我们进行了一项涉及1513例患者的回顾性研究,分为正常体重,超重,和肥胖类别使用校正后的BMI值。我们进行了比较分析,以探讨BMI与各种结局之间的关系:分娩方法,出生时的阿普加分数,胎儿窘迫的发生率,胎儿出生体重,妊娠相关病理的存在,以及产后出血的发生。描述性统计分析用于表征患者和新生儿的人口统计学和临床特征。
    结果:通过检查变量,例如分娩期间胎儿窘迫的发生,交货时的阿普加分数,以及交付方式,我们发现BMI升高与产程和分娩期间并发症之间存在关联.结果表明,较高的BMI与并发症增加和分娩方式的变化有关。
    结论:肥胖是育龄妇女中最常见的健康问题,需要长期护理。它可能导致许多与妊娠相关的疾病,并在分娩和分娩期间影响母亲和孩子。肥胖与较低的Apgar评分有关,胎儿窘迫的发生率增加,剖宫产分娩率较高。虽然母亲有严重并发症的绝对风险,胎儿,肥胖女性中新生儿的比例较低,在怀孕前采取健康的饮食和运动行为,理想情况下,或者尽可能早地怀孕,可以帮助减少怀孕期间体重的过度增加。
    Obesity, characterized by an excess of adipose tissue, has become a significant global health issue. The prevalence of obesity has increased markedly in recent decades worldwide, with a sharp rise also observed in developing countries, particularly in urban areas. Addressing obesity during pregnancy is crucial for several reasons and presents challenges for specialists in obstetrics and gynecology.
    OBJECTIVE: The aim of the present study was to investigate the correlation between obesity and its implications for childbirth.
    METHODS: We conducted a retrospective study involving 1513 patients, grouped into normal-weight, overweight, and obese categories using corrected BMI values. We performed comparative analyses to explore the association between BMI and various outcomes: the method of delivery, the Apgar score at birth, the incidence of fetal distress, fetal birth weight, the presence of pregnancy-associated pathologies, and the occurrence of postpartum hemorrhage. Descriptive statistical analysis was utilized to characterize the demographic and clinical features of the patients and newborns.
    RESULTS: By examining variables such as the occurrence of fetal distress during labor, the Apgar score at delivery, and the mode of delivery, we identified an association between increasing BMI and complications during labor and delivery. The results indicate that a higher BMI is linked with increased complications and variations in the mode of delivery.
    CONCLUSIONS: Obesity is the most common health issue among women of reproductive age and requires long-term care. It can contribute to numerous pregnancy-associated pathologies and affect both mother and child during labor and delivery. Obesity is associated with lower Apgar scores, the increased incidence of fetal distress, and a higher rate of cesarean section deliveries. Although the absolute risk of serious complications for mother, fetus, and newborn is low among women with obesity, adopting healthy eating and exercise behaviors prior to pregnancy, ideally, or as early in pregnancy as possible, can help minimize excessive weight gain during pregnancy.

    背景:罗布森十组分类系统(RTGCS)越来越多地用于评估,监视器,并比较医疗机构内部和之间的剖腹产(CS)率。我们使用RTGCS评估了乌干达北部古鲁地区转诊医院(GRRH)的CS率的主要贡献者。
    方法:我们对2019年6月至2020年7月在GRRH的所有分娩进行了回顾性分析,古鲁市,乌干达。我们审查了母亲的档案,并收集了有关社会人口统计学和产科变量的数据。结果变量是基于奇偶校验的罗布森十组(1-10),胎龄,胎儿介绍,胎儿数量,分娩的开始,平等和谎言,CS的历史
    结果:我们回顾了3,183例分娩的医疗记录,平均年龄24.6±5.7岁。总CS率为13.4%(n=427)。大多数参与者属于RTGCS第3组(43.3%,n=185)和1(29.2%,n=88)。CS最常见的适应症是分娩时间延长(41.0%,n=175),其次是胎儿窘迫(19.9%,n=85)和骨盆收缩(13.6%,n=58)。
    结论:我们的研究表明,GRRH患者的低风险产科人群主要是第3组和第1组的母亲,这可以解释13.4%的总CS率低。然而,低危人群的CS发生率高得惊人,这可能会导致未来CS费率的增加。我们建议通过CS审核进行针对特定群体的干预,以降低特定群体的CS率。
    BACKGROUND: The Robson Ten Groups Classification System (RTGCS) is increasingly used to assess, monitor, and compare caesarean section (CS) rates within and between healthcare facilities. We evaluated the major contributing groups to the CS rate at Gulu Regional Referral Hospital (GRRH) in Northern Uganda using the RTGCS.
    METHODS: We conducted a retrospective analysis of all deliveries from June 2019 through July 2020 at GRRH, Gulu city, Uganda. We reviewed files of mothers and collected data on sociodemographic and obstetric variables. The outcome variables were Robson Ten Groups (1-10) based on parity, gestational age, foetal presentation, number of foetuses, the onset of labour, parity and lie, and history of CS.
    RESULTS: We reviewed medical records of 3,183 deliveries, with a mean age of 24.6 ± 5.7 years. The overall CS rate was 13.4% (n = 427). Most participants were in RTGCS groups 3 (43.3%, n = 185) and 1 (29.2%, n = 88). The most common indication for CS was prolonged labour (41.0%, n = 175), followed by foetal distress (19.9%, n = 85) and contracted pelvis (13.6%, n = 58).
    CONCLUSIONS: Our study showed that GRRH patients had a low-risk obstetric population dominated by mothers in groups 3 and 1, which could explain the low overall CS rate of 13.4%. However, the rates of CS among low-risk populations are alarmingly high, and this is likely to cause an increase in CS rates in the future. We recommend group-specific interventions through CS auditing to lower group-specific CS rates.

    初次剖腹产的适应症范围随着胎次的增加而变化。随着胎次的进步,更多的剖宫产是针对产妇而不是胎儿的指征。这项研究的目的是确定先前有阴道分娩史的经产妇女剖宫产的指征和并发症。这项横断面描述性观察性研究于2019年1月至2019年6月在Mymensingh医学院附属医院对100名接受原发性剖腹产的有意选择的经产妇女进行了研究。一个精心设计的,半结构化问卷通过面对面访谈收集数据,临床检查和实验室检查。数据分析采用SPSS20.0版。本研究中大多数(74.0%)的女性在21-30岁年龄段,平均年龄为26.3±5.76岁。大多数患者是第二次妊娠(42.0%),其次是第三次妊娠(33.0%)。在这项研究中,最高的孕妇是第6位。大多数患者为第1段(44.0%)。本研究中最高的段落是第5段。在这项研究中,最常见的剖宫产指征是胎儿窘迫(26.0%)。下一个常见的适应症是头骨盆不相称(22.0%),产前出血(13.0%),mal-presentaion或mal-position(16.0%)。其他原因是PROM(8.0%),长期分娩(6.0%),脐带脱垂(2.0%),过期妊娠(4.0%),重度子痫前期(2.0%)和继发性低生育(1.0%)。在这项研究中没有产妇死亡的病例,但15名母亲患有各种术后并发症,如伤口感染(4.0%),UTI(4.0%),产褥期发热(3.0%),产后出血(3.0%)和麻痹性肠梗阻(1.0%)。分娩的婴儿中有97名是活产。在97例活产婴儿中,有11例(11.34%)是早产婴儿。在分娩的婴儿中,大多数(85.0%)具有良好的APGAR评分(7-10)。总而言之,可以说,多胎分娩的妇女需要与primigravida同样的关注。产妇需要良好的产科护理,以改善产妇和新生儿的结局,并且仍将剖腹产率保持在较低的水平。
    The spectrum of indications for primary caesarean section changes with advancing parity. As parity advances more cesarean section are done for maternal rather than fetal indications. The objective of this study was to determine the indications and complications of caesarean section in multiparous women with history of previous vaginal delivery. This cross-sectional descriptive observational study was conducted in Mymensingh Medical College Hospital from January 2019 to June 2019 among 100 purposively selected multiparous women who underwent primary caesarean section. A well-designed, semi-structured questionnaire was used to collect data by face-to-face interview, clinical examinations and laboratory investigations. Data analysis was conducted in SPSS 20.0 version. Majority (74.0%) of the women in this study were in the age group 21-30 years with mean age of 26.3±5.76 years. Majority of the patients were of second gravida (42.0%) followed by third gravida (33.0%). The highest gravida in this study was 6th. Most of the patients were of para 1(44.0%). Highest para in this study was para 5. The most common indication of caesarean section in this study was foetal distress (26.0%). The next common indications were cephalo-pelvic disproportion (22.0%), antepartum haemorrhage (13.0%), mal-presentaion or mal-position (16.0%). Other causes were PROM (8.0%), prolonged labour (6.0%), cord prolapse (2.0%), post-dated pregnancy (4.0%), severe pre-eclampsia (2.0%) and secondary subfertility (1.0%). There was no case of maternal mortality in this study but 15 mothers suffered from various post-operative complications like wound infection (4.0%), UTI (4.0%), puerperal pyrexia (3.0%), postpartum haemorrhage (3.0%) and paralytic ileus (1.0%). Among the babies delivered 97 were live births. Among the 97 live births 11(11.34%) were preterm babies. Among the babies delivered majority (85.0%) was with good APGAR score (7-10). In conclusion it can say that a multiparous women in labour requires the same attention as that of primigravida. A parous women needs good obstetric care to improve maternal and neonatal outcome and still keeping caesarean section to a lower rate.

    背景:产科合并症指数(OBCMI)是一种经过国际验证的孕产妇风险因素评分系统,旨在可靠地预测严重孕产妇发病率(SMM)的发生。这项回顾性队列研究将OBCMI应用于卡塔尔的孕妇,以验证其在预测SMM和累积胎儿发病率方面的性能。
    方法:从病历中提取了2021年7月在大型三级中心分娩的1000名妇女的数据。OBCMI指数包括孕产妇人口统计学,预先存在的合并症,和各种当前的妊娠危险因素,如高血压,包括先兆子痫,胎儿宫内死亡,胎膜长期破裂和未预订的怀孕。SMM基于ACOG共识定义,累积胎儿发病率(CFM)包括分娩时的胎儿窘迫,低APGAR和脐动脉(UA)pH,新生儿重症监护病房(NICU),和缺氧缺血性脑病(HIE)。计算c统计量或曲线下面积(AUC)以确定OBCMI预测SMM和CFM的能力。
    结果:该队列的OBCMI评分中位数为1(四分位数范围-0至2);50%的女性评分为0,而85%(n=842)的评分范围为0至2。10名女性(1%)得分≥7分;最高分为10分。SMM的发生率为13%。根据修改后的评分系统,发生SMM的患者OBCMI平均得分为2.18(±2.20)分,未发生SMM的患者平均OBCMI得分为1.04(±1.40)分(中位数为1,IQR:1-3,中位数为0,IQR:0-2;p<0.001).CFM发生率为11.3%。低APGAR评分的发生率,HIE和NICU的入院率接近千分之一。大约5%的婴儿在分娩时出现胎儿窘迫和低UApH值。OBCMI分数每增加1个单位,SMM的几率增加了44%(OR1.4495%CI1.30-1.59;p<0.001;AUC0.66),CFM增加28%(OR1.2895%CI1.15-1.42;p<0.001;AUC0.61)。截止评分为4具有很高的特异性(>90%);OBCMI评分≥4的女性中有1/4和1/6出现SMM和CFM,分别。
    结论:OBCMI在预测卡塔尔孕妇的SMM方面表现良好,可以有效地用作危险评估工具,以预防高危病例,从而可以及时开展适当的多学科护理,以降低SMM和孕产妇死亡率。该指数也有助于预测胎儿发病率;然而,需要进一步的前瞻性研究来验证CFM的OBCMI.
    BACKGROUND: The Obstetric Comorbidity Index (OBCMI) is an internationally validated scoring system for maternal risk factors intended to reliably predict the occurrence of severe maternal morbidity (SMM). This retrospective cohort study applied the OBCMI to pregnant women in Qatar to validate its performance in predicting SMM and cumulative fetal morbidity.
    METHODS: Data from 1000 women who delivered in July 2021 in a large tertiary centre was extracted from medical records. The OBCMI index included maternal demographics, pre-existing comorbidities, and various current pregnancy risk factors such as hypertension, including preeclampsia, intrauterine fetal death, prolonged rupture of membranes and unbooked pregnancies. SMM was based on the ACOG consensus definition, and the cumulative fetal morbidity (CFM) included fetal distress in labour, low APGAR and umbilical artery (UA) pH, admission to neonatal intensive care (NICU), and hypoxic-ischemic encephalopathy (HIE). A c-statistic or area under curve (AUC) was calculated to determine the ability of OBCMI to predict SMM and CFM.
    RESULTS: The median OBCMI score for the cohort was 1 (interquartile range- 0 to 2); 50% of women scored 0, while 85% (n = 842) had a score ranging from 0 to 2. Ten women (1%) scored ≥ 7; the highest score was 10. The incidence of SMM was 13%. According to the modified scoring system, the mean OBCMI score in those who developed SMM was 2.18 (± 2.20) compared to a mean of 1.04 (± 1.40) in those who did not (median 1, IQR:1-3 versus median 0, IQR: 0-2; p < 0.001). The incidence of CFM was 11.3%. The incidence of low APGAR score, HIE and NICU admission was nearly 1 in 1000. Around 5% of the babies had fetal distress in labour and low UA pH. For every 1 unit increase in OBCMI score, the odds of SMM increased by 44% (OR 1.44 95% CI 1.30-1.59; p < 0.001; AUC 0.66), and CFM increased by 28% (OR 1.28 95% CI 1.15-1.42; p < 0.001; AUC 0.61). A cut-off score of 4 had a high specificity (> 90%); 1 in 4 and 1 in 6 women with OBCMI score ≥ 4 developed SMM and CFM, respectively.
    CONCLUSIONS: The OBCMI performed moderately well in predicting SMM in pregnant women of Qatar and can be effectively used as a risk assessment tool to red-flag high-risk cases so that appropriate and timely multidisciplinary care can be initiated to reduce SMM and maternal mortality. The index is also helpful in predicting fetal morbidity; however, further prospective studies are required to validate OBCMI for CFM.

    脐动脉血栓形成(UAT)是一种罕见的妊娠并发症,与不良妊娠结局有关,包括胎儿宫内窘迫,宫内生长受限,仍然出生。UAT是不可预测的,产前诊断是具有挑战性的。对UAT的治疗策略没有共识,尤其是对有脐动脉栓塞产前检测的患者。在大多数以前的情况下,进行了紧急剖宫产,或宫内胎儿死亡发生在UAT诊断时。
    在本报告中,我们描述了一例34岁女性在妊娠31+3周时通过常规超声检查发现的其中一条脐动脉血栓形成的病例.经过预期管理和4天的密集监测,由于胎儿脐带血流和大脑中动脉血流异常,进行了紧急剖宫产;新生儿出生时状况良好。最终的脐带组织病理学显示其中一个脐动脉血栓形成。在这种情况下,母亲和新生儿都接受了将近2年的长期随访,目前身体健康,没有任何并发症。
    根据我们的经验,在怀疑UAT时,产科医生应综合考虑当前的胎龄和胎儿宫内状况,以确定最佳分娩时间。在胎儿未成熟时,只要母亲和胎儿稳定,应延长适当的胎龄,尽最大努力完成皮质类固醇治疗促进胎儿肺成熟和硫酸镁保护胎儿大脑。在期待管理期间,超声监测,电子胎心监护,应加强胎动计数。临床医生应确保患者及其家人了解UAT预期管理的所有潜在风险。
    UNASSIGNED: Umbilical artery thrombosis (UAT) is a rare complication of pregnancy and is associated with adverse pregnancy outcomes, including fetal intrauterine distress, intrauterine growth restriction, and still birth. UAT is unpredictable, and prenatal diagnosis is challenging. There is no consensus on the treatment strategy of UAT, especially for patients with prenatal detection of one of the umbilical artery embolisms. In most previous cases, an emergency cesarean section was performed, or intrauterine fetal death occurred at the time of UAT diagnosis.
    UNASSIGNED: In this report, we describe a case of thrombosis in one of the umbilical arteries detected by routine ultrasonography at 31+3 weeks of gestation in a 34-year-old woman. Following expectant management with intensive monitoring for 4 four days, an emergency cesarean section was performed because of abnormal fetal umbilical cord blood flow and middle cerebral artery blood flow; the newborn was in good condition at birth. The final umbilical cord histopathology revealed thrombosis in one of the umbilical arteries. Both mother and newborn described in this case underwent long-term follow-up for nearly 2 two years and are currently in good health without any complications.
    UNASSIGNED: Based on our experience, obstetricians should comprehensively consider the current gestational age and fetal intrauterine status when UAT is suspected to determine the best delivery time. The appropriate gestational age should be prolonged as long as the mother and fetus are stable when the fetus is immature, trying our best to complete the corticosteroid treatment to promote fetal lung maturity and magnesium sulfate to protect fetal brain. During expectant management, ultrasound monitoring, electronic fetal heart monitoring, and fetal movement counting should be strengthened. Clinicians should ensure that the patients and their families are informed about all potential risks of expectant management for UAT.

    目的:阐明动脉和静脉多普勒超声参数与胎龄较小(SGA)胎儿产时胎儿受损(IFC)和新生儿酸中毒二次剖宫产风险之间的关系。
    方法:这种单中心,prospective,失明,队列研究包括单胎妊娠,其估计胎儿体重(EFW)<36孕周以上10分。纳入研究后,所有女性都接受了多普勒超声检查,包括脐动脉(UA)搏动指数(PI),大脑中动脉(MCA)PI,胎儿主动脉峡部(AoI)PI,脐静脉血流量(UVBF),和改良心肌性能指标(mod-MPI)。主要结局定义为IFC二次剖宫产。
    结果:总计,包括87次SGA怀孕,其中16%需要为IFC剖腹产。这些胎儿的腹围(AC)校正后的UVBF较低(5.2(4.5-6.3)vs7.2(5.5-8.3),p=0.001)。比较AoIPI时没有差异,UAPI,ACMPI,或mod-MPI。未发现新生儿酸中毒的关联。经过多变量逻辑回归,由于IFC,UVBF/AC与剖宫产保持独立相关(aOR0.61[0.37;0.91],p=0.03),曲线下面积(AUC)为0.78(95%CI,0.67-0.89)。由于IFC,UVBF/AC的第50百分位设定的临界值达到86%的敏感性和58%的特异性(OR8.1;95%CI,1.7-37.8,p=0.003)。
    结论:脐静脉血流量(UVBF/AC)水平低与IFC剖宫产SGA胎儿的风险增加相关。
    OBJECTIVE: To elucidate the association between arterial and venous Doppler ultrasound parameters and the risk of secondary cesarean delivery for intrapartum fetal compromise (IFC) and neonatal acidosis in small-for-gestational-age (SGA) fetuses.
    METHODS: This single-center, prospective, blinded, cohort study included singleton pregnancies with an estimated fetal weight (EFW) < 10th centile above 36 gestational weeks. Upon study inclusion, all women underwent Doppler ultrasound, including umbilical artery (UA) pulsatility index (PI), middle cerebral artery (MCA) PI, fetal aortic isthmus (AoI) PI, umbilical vein blood flow (UVBF), and modified myocardial performance index (mod-MPI). Primary outcome was defined as secondary cesarean section due to IFC.
    RESULTS: In total, 87 SGA pregnancies were included, 16% of which required a cesarean section for IFC. Those fetuses revealed lower UVBF corrected for abdominal circumference (AC) (5.2 (4.5-6.3) vs 7.2 (5.5-8.3), p = 0.001). There was no difference when comparing AoI PI, UA PI, ACM PI, or mod-MPI. No association was found for neonatal acidosis. After multivariate logistic regression, UVBF/AC remained independently associated with cesarean section due to IFC (aOR 0.61 [0.37; 0.91], p = 0.03) and yielded an area under the curve (AUC) of 0.78 (95% CI, 0.67-0.89). A cut-off value set at the 50th centile of UVBF/AC reached a sensitivity of 86% and specificity of 58% for the occurrence of cesarean section due to IFC (OR 8.1; 95% CI, 1.7-37.8, p = 0.003).
    CONCLUSIONS: Low levels of umbilical vein blood flow (UVBF/AC) were associated with an increased risk among SGA fetuses to be delivered by cesarean section for IFC.

    通过胎粪污染的羊水(MSAF)出生的新生儿在出生时心肺转换改变的风险增加。很少有文献评估这些新生儿的过渡血流动力学。我们旨在通过超声心动图评估通过MSAF出生的新生儿的过渡血流动力学,与健康的新生儿相比。主要目的是使用左肺动脉速度时间积分(LPA-VTI)评估肺血管阻力。次要目标是评估其他肺血管参数和心肌功能。我们招募了35名MSAF出生的新生儿和35名健康的新生儿。由儿科心脏病专家在生命的24和48小时进行超声心动图检查。比较MSAF出生新生儿和健康新生儿的超声心动图参数,以及发生胎粪吸入综合征(MAS)和未发生(非MAS)的MSAF出生新生儿之间。在35名MSAF出生的新生儿中,14人(40%)无活力,18人(51%)需要入住新生儿重症监护病房,8(23%)开发了MAS,3(9%)肺动脉高压和1(3%)漏气。在超声心动图上,MSAF出生的新生儿在24和48h时LPA-VTI(cm;平均值±SD)显着降低(14.38±2.48;15.55±2.48),与健康新生儿相比(16.60±2.14;17.66±2.71),分别。Further,在MAS中,LPA-VTI在24和48h显着降低(11.81±3.0;12.43±2.5),与非MAS新生儿相比(15.15±1.72;16.48±1.55),分别。两组其他肺血管和心肌功效参数具有可比性。MSAF新生儿的肺适应明显延迟,这在MAS新生儿中更为明显。进一步的研究应探索这些参数在该人群中早期预测心肺疾病的实用性。
    Neonates born through meconium-stained amniotic fluid (MSAF) are at increased risk of altered cardiopulmonary transition at birth. There is a paucity of literature evaluating the transitional hemodynamics in these neonates. We aimed to evaluate transitional hemodynamics via echocardiography in neonates born through MSAF, compared to healthy neonates. The primary objective was to assess pulmonary vascular resistance using left pulmonary artery-velocity time integral (LPA-VTI). The secondary objectives were to assess other pulmonary vascular parameters and myocardial function. We enrolled 35 MSAF-born and 35 healthy neonates. Echocardiography was performed at 24 and 48 h of life by a pediatric cardiologist. Echocardiographic parameters were compared between MSAF-born and healthy neonates, and between MSAF-born neonates who developed meconium aspiration syndrome (MAS) and who did not (non-MAS). Among 35 MSAF-born neonates, 14 (40%) were non-vigorous, 18 (51%) required admission to neonatal intensive care unit, 8 (23%) developed MAS, 3 (9%) pulmonary hypertension and 1 (3%) air leak. On echocardiography, LPA-VTI (cm; mean ± SD) was significantly decreased at 24 and 48 h in MSAF-born neonates (14.38 ± 2.48; 15.55 ± 2.48), compared to healthy neonates (16.60 ± 2.14; 17.66 ± 2.71), respectively. Further, LPA-VTI was significantly reduced at 24 and 48 h among MAS (11.81 ± 3.0; 12.43 ± 2.5), compared to non-MAS neonates (15.15 ± 1.72; 16.48 ± 1.55), respectively. Other pulmonary vascular and myocardial function parameters were comparable between the two groups. Pulmonary adaptation was significantly delayed in neonates with MSAF, which was more pronounced in MAS neonates. Further studies should explore the utility of these parameters for early prediction of cardiorespiratory morbidities in this population.

  • 文章类型: Journal Article
    目的:探讨不同治疗方法治疗持续性枕位的可行性及对母婴并发症的影响。
    方法:在我院于2020年4月至2023年3月进行的阴道分娩试验中,子宫颈完全扩张,显示位于+2站。九十六名孕妇在+4站出现胎儿,胎儿位置,产妇并发症,第二产程异常,和/或胎儿窘迫分为两组:65例Kielland产钳阴道分娩和31例急诊剖宫产。交货时间,阴道裂伤率,产后失血量,产褥期感染率,新生儿出生伤害率,并对新生儿1minApgar评分进行分析。
    结果:分析96例孕妇的分娩结局及母婴并发症:应用Kielland产钳分娩时间较短,而阴道裂伤率,产后出血,产褥感染率明显低于急诊剖宫产组,新生儿1minApgar评分高于急诊剖宫产组(p<0.05)。
    结论:当存在持续性枕横位并且需要加快分娩时,在阴道分娩中使用Kielland镊子在临床上是合适的。使用Kielland镊子可以缩短分娩时间,提高阴道分娩成功率,减少母婴并发症。
    OBJECTIVE: To explore the clinical feasibility of different treatment methods for persistent occipitotransverse position and the influence on maternal and infant complications.
    METHODS: During the trial of vaginal delivery from April 2020 to March 2023 in our hospital, the cervix was fully dilated and the presentation was located at +2 station. Ninety-six pregnant women with fetal presentation at +4 station, occipitotransverse fetal position, maternal complications, abnormalities in the second stage of labor, and or fetal distress were divided into two groups: 65 patients with Kielland forceps vaginal delivery and 31 patients underwent emergency cesarean section. The delivery time, vaginal laceration rate, postpartum blood loss volume, puerperal infection rate, neonatal birth injury rate, and neonatal 1 min Apgar scores were analyzed.
    RESULTS: The delivery outcomes and maternal and neonatal complications of 96 pregnant women were analyzed: the application of Kielland forceps delivery time was shorter, while the vaginal laceration rate, postpartum hemorrhage, puerperal infection rate were significantly lower than that of patients undergoing emergency cesarean section and the neonatal 1 min Apgar score was higher than that of emergency cesarean section group (p < 0.05).
    CONCLUSIONS: It was clinically appropriate to use Kielland forceps in vaginal delivery when the persistent occipitotransverse position was present and delivery needed to be expediated. Use of Kielland forceps can shorten the delivery time, improve the success rate of vaginal delivery and reduce the complications of mothers and infants.
